 DBW, SBW series single-, three-phase automatic compensation power regulator is the introduction of absorbing advanced technology in Western Europe, combined with our national conditions, designed to stabilize the AC voltage when the external power supply network voltage fluctuations or load changes caused by can automatically maintain the stability of the output voltage when the voltage fluctuation. The products in this series compared with other types of regulator, with a large capacity, high efficiency, no waveform distortion, stable voltage regulation, etc., widely applicable load, able to withstand transient overload, long-term continuous work, manual / automatic switching, The voltage regulator / power switch with overvoltage, undervoltage protection, calls self-recovery function, as well as small size, light weight, easy installation, reliable operation. 

 · Use the occasion 


 Widely used in post offices, stores, elevators, hospitals, schools, printing, securities and other occasions and all of the required voltage is normal, medium-sized industrial and mining enterprises workshop, part of the power supply and critical equipment and stand-alone supporting.
